The sensors help assist the All-Star coaches and trainers in learning if any players should be checked for concussions. A red light goes off on the device after a hard hit. Players wore them in practice this week.

"It's a step in the right direction," said South coach Jake Gilbert, the Westfield coach. "If we can use technology to help us protect kids. Why not?"

The device was provided on a free trail basis for the All-Stars.

Gilbert said the device will be available to his Westfield players this season.

Former Westfield High School quarterback Nick Ferrer and offensive lineman Zane Burtron are both playing for Gilbert's South squad.

Ferrer, who is headed to University of Saint Francis in Fort Wayne and is playing for the South squad, said he likes the concept.

"It really only goes off with a really hard hit," Ferrer said. "It's not that sensitive. So if it goes off, you probably have a concussion and the trainer can see if you have any symptoms."

Ferrer said it would be good for every team to have it.

"A lot of guys play the tough guy role," Ferrer said. "But this is good because once you get the red light you have to get checked out."

The Olivet Nazarene-bound Burtron sees the value as well

"As a lineman you're hitting every play," Burtron said. "It's a good thing to have if your form slips or don't do something your coach tells you to do (technique wise), it's a good backup plan to have it on."
